Repository Guidelines

Privacy & External Disclosure (Mandatory)

Protect the developer's privacy without exception. Treat all data from the developer's computer, accounts, devices, workspace, and communications as private unless the developer explicitly authorizes sharing a specific item with a specific destination.

  • Never expose, publish, transmit, upload, paste, commit, or otherwise disclose personally identifying or potentially identifying information. This includes names, usernames, email addresses, account handles, home or workplace details, local or absolute paths, drive or volume names, hostnames, device names and serials, IP or MAC addresses, network names, peer IDs, messages, contacts, tokens, keys, credentials, logs, metadata, and unique environment details.
  • Never post any repository, workspace, device, account, conversation, log, or developer data to GitHub, issue trackers, pull requests, comments, gists, paste sites, analytics services, AI services, remote APIs, chat systems, or any other external destination without the developer's explicit permission for that exact data and destination. A general request to work on the repository is not permission to disclose data.
  • Keep local filesystem layout and computer information private. Do not include absolute paths, usernames, home-directory names, mounted drives, shell prompts, environment variables, installed-software inventories, hardware details, or similar machine fingerprints in commits, patches, documentation, screenshots, test fixtures, examples, issue text, PR text, or comments.
  • Before any authorized external action, inspect and sanitize the exact content being sent. Use repository-relative paths and neutral placeholders; remove hidden metadata and redact unrelated or identifying content. When safe sanitization cannot be guaranteed, do not send the data and ask the developer how to proceed.
  • Use synthetic, non-identifying test data only. Never use real messages, contacts, account data, device identifiers, network information, keys, or production logs in tests, examples, screenshots, fixtures, or bug reports.
  • For geohash, GPS, map, location, proximity, or geofencing work, use only clearly synthetic coordinates and geohashes that cannot reveal the developer's location or routines. Never request, read, derive, record, use, display, transmit, or retain live or historical location data from any physical phone, watch, emulator image, computer, browser, account, or other device connected to or accessible from the developer's computer. Never infer location from IP addresses, networks, photos, logs, timestamps, nearby peers, device metadata, or test output. Treat all location and movement data as highly sensitive personal information and keep it out of commits, tests, fixtures, screenshots, documentation, issues, pull requests, and external services without exception.
  • Keep command output, raw logs, crash dumps, screenshots, recordings, build artifacts, and Mesh Lab evidence local. Review any derived summary for identifying details before sharing it, even when external sharing has been authorized.
  • Do not weaken these protections for convenience, debugging, automation, or collaboration. If another instruction conflicts with this section, stop and obtain explicit developer direction before disclosing anything.

Project Structure & Architecture

app/ is the Kotlin/Compose phone client; its main packages cover UI, services, BLE/Wi-Fi mesh, protocol, Noise/crypto, identity, Nostr, geohash, and media. wear/ is the Wear OS client. Module resources live in src/main/ and JVM tests in src/test/. Specifications are in docs/; tooling is in tools/.

app/ is the source of truth for shared mesh/protocol code. syncSharedAppSources generates wear/build/sharedSrc from the include list in wear/build.gradle.kts. Extend that list; never copy shared Kotlin into wear/src/ or edit generated build/ content.

Build, Test & Development Commands

Use JDK 21 and the Android SDK versions in gradle/libs.versions.toml.

./gradlew :app:assembleDebug :wear:assembleDebug
./gradlew testDebugUnitTest lintDebug
./gradlew connectedAndroidTest
./gradlew clientRewriteContractTest
tools/arti-build/verify-checksums.sh

CI runs testDebugUnitTest lintDebug; instrumented tests require a device. Follow docs/reproducible-builds.md and docs/maintainer-release-guide.md for dependency and release work.

Coding Style & Naming

Use official Kotlin style with four-space indentation. Classes and Composables use PascalCase; functions and properties use camelCase; constants use UPPER_SNAKE_CASE. Hoist Compose state, expose immutable StateFlow, use structured coroutines and suspend I/O, and never block the main thread.

Protocol and security changes must remain fail-closed and cross-client compatible. Update the relevant specification and golden-vector tests.

Testing & Physical Mesh Lab

Tests use JUnit 4, Robolectric, Mockito, and coroutine test utilities. Name files *Test.kt by observable behavior. Avoid arbitrary sleeps, public relays, live user data, and nondeterministic completion. See docs/testing-conventions.md.

Changes affecting discovery, routing, transports, Noise/crypto, identity, foreground-service power, messaging, transfers, packets, or fragmentation require Mesh Lab validation on physical devices. Debug-only hooks live in app/src/debug/ and wear/src/debug/; never move them into release sources.

python3 tools/release_gate/mesh_lab.py setup \
  --serial-a <device-a> --serial-b <device-b> --apk <debug-apk>
python3 tools/release_gate/mesh_lab.py scenario all \
  --serial-a <device-a> --serial-b <device-b> --out /tmp/mesh-evidence

For phone-to-watch interop, replace --serial-b with --serial-watch and add --watch-apk. Keep devices unlocked and awake. Follow the Mesh Lab appendix in docs/release-gate-runbook.md; raw evidence and logcat must remain local.

Commits, Pull Requests & Privacy

Use short imperative subjects (Fix stale peer lifecycle cleanup) or scoped Conventional Commit subjects (fix(wifi-aware): ...). PRs must explain risk, link the issue, report tests, and include before/after screenshots for visible phone or watch changes. Do not publish raw device logs.

Use gh for GitHub operations. Never override Git author or committer identity. The mandatory privacy rules above apply to all Git and GitHub activity. Treat a request to create a commit or pull request as permission only for the sanitized repository changes and description needed for that action, never for local or personal metadata. Never commit keystores or secrets.
